ment in Can-Heading Machines; and ,I declare the following to be a full,clear, and

exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification.

My invention has for its object the production of a can-headingmachine-that is, a machine adapted to place the ends or heads on thebodies of sheet-metal cans; and it consists in a combination of devicesand appliances hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of the machine. Fig. 2 isaside elevation. Fig. 3 is a detail illustrating the can-feedingmechanism. Fig. 4. is a sectional view on the line t 4. of Fig. 1. Fig.5 is a sectional view on the line 5 5 of Fig. 1. Fig. 6 is a plan viewof one of the reciprocating heads. Fig. 7 is a section on the line 7 7of Fig. 6. Fig. 8 is a sectional View on the line 8 8 of Fig. 7. Fig. 9is a sectional view on the line 9 9 of Fig. 7. Fig. 10 isan endelevation of the head. Fig. 11 is a detail of one of the bell-cranklevers. Fig. 12 is afront elevation of the feeding-head. Fig. 13 is anenlarged detail of the portion of the head shown in Fig. 7. Figs. 14 and15 are details illustrating the cam movements.

In carrying out the invention, A represents the main frame of themachine, 13 the main shaft, 0 the drive-wheel.

Referring to Fig. 1, it' will be seen that there is a can-runway D, downwhich the cans are fed, and on each side thereof can-head runways E E,down which the can-heads are fed.

A are suitable standards extending from the main frame A, havinghearings in their upper ends A to support the reciprocating parts of theheading mechanism, as hereinafter explained.

' F is a reciprocating frame carried in the bearings A (Shown in detailin Figs. 6 and 7 l G is a stem movable in the reciprocating frame F andhaving on its end a plate H. On this stem, supported by the bearing J,is a frame made up of two arms J J one being above and the other belowthe stem, these arms extending through the flange f of the reciprocatingframe F and engaged to a ring K by screws 3'.

F isa ring engaged to the flange f of the reciprocating frame F. Engagedto the face of the ring F by the bolts f is another ring F 1 The ring Fand the ring F have their opposing. faces channeled to receive the ringK, the channel for said ring K being slightly larger than the ring, sothat 'the latter may reciprocate therein.

M is a series of what may be termed bellcrank levers, shaped, as shownin Fig. 11, with rounded bearingsurfaces m m to fit in the correspondingrounded faces m m of the rings F F. Each of the levers is rounded on itsend, as at m, to fit in the channel 7c in the face of the ring K, whilethe other end of the lever is provided with a rounded end m and ashoulder m". i

It will be observed by reference to Fig. 8 that the entire circumferenceof the rings is filled with the levers M. In the face of the ring F isan opening or slot F (shown in Figs. 6 and 9,) the can-head terminatingad jacent to this slot or opening. Supported from suitable hangers AFig. 1, is a shaft N. Pivoted on this shaft is an arm N, Fig.

3, carrying on its upper end a cross-head N Fig. 12. The latter isshaped with a pusherplate N at each end for feeding the can-heads andwith a circular portion N for feeding the can-bodies.

On the main shaft' B of the machine, as shown in Fig. 4, is a cam N andon the arm N are rollers a, one for each side of the cam, so that as the'cam is revolved the arm N is .reciprocated, and consequently thecross-head pivoted to the lever O and passing through the short arm ofthe lever O, carries a spring 0 which bears upon the lever O and tendsnormally to keep the latter upon the can which is fed against it.

0n the main shaft B, Fig. 4, is a cam P for reciprocating the frame F,and consequently the head as a whole. This is accomplished by means ofthe roller P, traveling in the cam-groove P P P are levers to which theroller P is pivoted, each extending to a shaft P Figs. 5 and 15. On thisshaft is an arm P, which extends up to a point adjacent to thereciprocating frame F. Engaged to this frame is an arm P and a link P ispivoted to the arm P and to the upper end of the lever P thus connectingthem. Thus a revolution of the cam P tends to alternately elevate anddepress the joined ends of the levers P P, and each frame F is thusreciprooated. On each shaft P on each side of the machine, is a lever Q,and as both sides of the machine are duplicates I will proceed todescribe but one side. Q is an arm keyed to the stem G,Figs. 5 and 14c,and connected with the upper end of the lever Q by the link Q The leverQ, is a bell-crank lever with the end provided with a roller Q whichtravels in the camgroove Q of the cam Q so that as the shaft is revolvedthe lever Q, is tilted, and consequently reciprocates the stem G, and asthe levers Q for each side of the machine are pivoted together, as shownin Figs. 4 and 14 both stems G will be simultaneously reciprocated.Pivoted atj to the frame J is alink R, Figs. 1 and 6. Supported on thereciprocating frame F is a bearing R, carrying a shaft on which the twoarms R R are engaged, the end of the link B being pivoted to the end ofthe arm R Pivoted to the end of the arm R Fig. 1, is a rod R whichextends down and is pivoted to a lever B, and the other end of the saidlever B being pivoted on the shaft P on the opposite side of themachine, Fig. 1. This causes the two levers R to cross each other, andat the point where they cross is provided a roller R which travels inthe cam-groove R of the cam R, the latter beingon the shaft B. Thus arevolution of the cam R alternately raises and lowers the two levers Rand they, through the rods R and links R reciprocate the frame J.

The operation is as fo lows: A revolution of the main shaft B operatesthe entire mechanism, and I will first describe the operation of thecan-head-feeding mechanism. A revolution of the cam N on the shaft Bcauses the arm N to reciprocate back and forth underneath the can andcan-head chutes D E E. The portion N of the cross-head on the arm Npicks up a can and throws it forward, as shown in Fig. 3, the fiatportion n serving to keep the balance of the cans in the chute. Thelever 0 holds the can in place while the heads are being put on, and asthe arm N recedes to pick up another can the can will drop to thedelivery-chute D and be held there by the lever 0 until the arm N againcomes forward, when the portion n will serve to throw the can down thechute, as shown in Fig. 3. The feeding of the can-heads is simultaneouswith the can-bodies, the canheads being thrown forward into the headingmechanism by the cross-heads N (Shownin Figs. 2 and 12.) As thecan-bodies and canheads reach their respective positions the cans are soarranged thatthe cam Q will first come into play and will, through thelever Q and link Q throw the stem G, Fig. 7, forward, carrying with itthe head H, which, engaging the can-head, forces the latter to theposition shown by the dotted lines, Fig. 13. As soon as this isaccomplished the cam P comes into play, and through the levers P P andlink P the frame F, and consequently the entire head, is moved forward,so that the end of the can-body is caused to enter the head, as shown bythe dotted lines S, Fig. 13. The end of the can-body is guided into itscan end by the beveled face S of the head and beveled face an of thelevers M. Up to this time the cams P R have moved simultaneously or inunison; but as soon as the can-body has entered the can-head thearrangement of the cams is such that the rod R will, through the lever Rand cam R, be thrown upward, and this action through the shaft R, link Rand link R will draw back the fitting J, and consequently will move thering K in its bearing, and the movement of the ring K will tilt thebell-crank levers M and throw the end m upward, as shown by the dottedlines in Fig. 13, thus releasing the can-head. The cam P now comes intoplay again and draws back the frame F, the stem G and head II remainingstationary, however, to hold the can-head in place on the can-body untilthe main head is drawn back entirely clear of the can-body, when the camQ again comes into play and carries the stem G and head H back, when thecan drops down, as shown in Fig. 3, to the delivery-chute D and iscarried away.

It is of course obvious that many details of the above-describedconstruction might be altered without departing from the spirit of myinvention.
